Early changes in prodynorphin mRNA and ir-dynorphin A levels after kindled seizures in the rat

, 1995
Prodynorphin mRNA and immunoreactive dynorphin A (ir‐dynorphin A) levels were measured in different brain areas at various time points after amygdala kindled seizures.

CRF1-R activation of the dynorphin/kappa opioid system in the mouse basolateral amygdala mediates anxiety-like behavior.

PLoS ONE, 2009
Stress is a complex human experience and having both rewarding and aversive motivational properties. The adverse effects of stress are well documented, yet many of underlying mechanisms remain unclear and controversial. Here we report that the anxiogenic

The dynorphin/kappa opioid receptor mediates adverse immunological and behavioral outcomes induced by repetitive blast trauma

Journal of Neuroinflammation, 2022
Background Adverse pathophysiological and behavioral outcomes related to mild traumatic brain injury (mTBI), posttraumatic stress disorder (PTSD), and chronic pain are common following blast exposure and contribute to decreased quality of life, but ...

Endogenous Opioid Levels Do Not Correlate With Itch Intensity and Therapeutic Interventions in Hepatic Pruritus

Frontiers in Medicine, 2021
Background: Chronic pruritus affects up to 70% of patients with immune-mediated hepatobiliary disorders. Antagonists of the μ-opioid receptor (MOR) and agonists of the κ-opioid receptor (KOR) are used to treat hepatic itch, albeit with limited success ...

Dynorphin (1-17): Lack of analgesia but evidence for non-opiate electrophysiological and motor effects [PDF]

, 2006
Dynorphin and an opiate-inactive fragment des-Tyr-dynorphin produced similar effects on EEG, motor function and hippocampal unit firing. Naloxone had no effect on the actions of dynorphin in these systems and dynorphin failed to produce analgesia upon ...

Ester hydrolysis differentially reduces aconitine-induced anti-hypersensitivity and acute neurotoxicity: Involvement of spinal microglial dynorphin expression and implications for Aconitum processing

Frontiers in Pharmacology, 2016
Aconitines, including bulleyaconitine A, probably the most bioactive and abundant alkaloids in Aconitum plant, are a group of diester C19-diterpenoid alkaloids with one acetylester group attached to C8 of the diterpenoid skeleton and one benzoylester ...

Estradiol treatment prevents injury induced enhancement in spinal cord dynorphin expression.

Frontiers in Physiology, 2012
Administration of the ovarian steroid estradiol in male and female animals has been shown to have neuromodulatory and neuroprotective effects in a variety of experimental models. In the present study, spinal tissues from dermatomes just above (T5-7, at

Enhanced dynorphin expression and secretion in pancreatic beta-cells under hyperglycemic conditions

Molecular Metabolism
Objective: Dynorphin, an endogenous opioid peptide predominantly expressed in the central nervous system and involved in stress response, pain, and addiction, has intrigued researchers due to its expression in pancreatic β-cells.

Ginsenoside Re protects methamphetamine-induced dopaminergic neurotoxicity in mice via upregulation of dynorphin-mediated κ-opioid receptor and downregulation of substance P-mediated neurokinin 1 receptor

Journal of Neuroinflammation, 2018
Background We previously reported that ginsenoside Re (GRe) attenuated against methamphetamine (MA)-induced neurotoxicity via anti-inflammatory and antioxidant potentials.
